Actually this can't work out (thanks to Kyösti for pointing that out).
Because the gpiobase address is in the separated i/o address space of
the cpu. "The control for the general purpose I/O signals is handled
through a separate 64-byte I/O space."
I am not aware of any distributed binaries that work similar to setpci
but in the i/o space, so you would need to program your own... like the
one described here:
